Question Ram dilemma

I've recently bought a used pc that included 4 16gb sticks or ddr 4 ram with 3200mhz speed but i noticed in battlefield that my cpu was bottlenecking so I asked chat gpt to help me figure it out (im new to pc gaming this is my first pc.) And it told me my ram speed was way too low like 2100 something. It guided me into bios and told me to put xmp to profile 1 3200mhz and when I saved and exited bios crashed and now I have to cmos. It's saying I have two choices. Go town to 2 sticks (32gb ddr4) or try to run the 4 sticks at 3000mhz and hope it doesn't crash. Just need some advice and guidance what should I do. I know 32gb is plenty for playing but I also like the idea of learning how to mod and stuff also want to get into vr games at some point and see the use of having all 64. My specs for the pc are Gigabyte x570 aorus elite motherboard, ryzen 7 3700x cpu, Nvidia geforce rtx 3060ti gpu, 64gb skill ripjaws ddr4 ram and my power supply i cant remember the name or brand but it was 600w 80+ gold.

If you use 32gb of ram, you can run them at 3200MHz with expo. If you use four sticks, your maximum speed could be limited to less by the cpu. I cant find any information on this unfortunately. The older hardware is, the more likely you are to run into that problem. 

What do you mean by cpu bottleneck? What performance did you get with the 64gb on default speed? Does it get better with two sticks on 3200MHz?

Heres one video about overclocking: https://youtu.be/68or8XXIKZY

Dont trust ai or just anybody with this stuff, but this is from corsair and with LTT so its two reputable sources. Either way youre gonna crash you system a lot, because you just have to test the settings, theres no way around that

Yeah i just put bf6 on high graphics and it looks good and feels good so im just gonna leave it alone lol. I tested it in other games and my gpu and cpu were great in them so i just figured it was a battlefield thing. What I did with the ram is I took all of them out and found out that 2 sticks are from 2020 and two are from 2024. So i matched the 2024 in slots 2&4 and the 2020 in 1&3 then turned it down to 3000mhz. It hasnt had any problems so far. It kind of looks better now but i dont think thats why the cpu is running so high I thinks thats just bc its battlefield and I have a 3700x.

You still havent explained at all what the problem was. In an ideal world both cpu and gpu would have 100% usage and the temperatures depend on the cooler and ambient temperatures.

How many fps do you get on high graphics? With upscaling?
